REVOLVING DOOR WITH CLOSING DEVICES AND PACKINGS.

To all whom it may concern Be it known that I, WALTER S. ELY, a citizenof the United States, residing at 18 Ash street, Flushing, borough ofQueens, and State of New York, have invented certain new and usefulImprovements in Revolving Doors with Closing Devices and Packings, fullydescribed and represented in the following specification and theaccompanying drawings, forming a part of the same.

The present invention relates to the revolving doors which are oftenapplied to the entrance of a building to exclude w nd and dust; and theobject of the invention is to avoid the necessity of providing foldinggates or sliding doors in addition to such revolving door, for closingand barr ng the passageway therethrough. Thls ob ect is attained in thepresent invention by forming the curved walls of the casing agalnstwhich the door-wings revolve, so that the whole or a part of such wallsmay he slid, bodily across the passageway and thus bar the same. 7

The segments of the casing-walls winch are movable across the passagewaymay be suspended from the roof and supported thereon in moving from oneposition to the other; or guides may be provided upon the floor or roofand the segments provided with rolls or wheels to ease their movement insuch guides. The entire casing-wall may be moved around the center ofthe casing to close the doorway, or only segmental portions of the twoside-walls may be made movable, suflicient to close the doorway whenmoved together, across the same.

The movable segments are, in practice, formed with locking-bolts orother means, by which they may be secured in their nor mal position atthe sides of the passageway, or in their position across the same so asto wholly bar the doorway.

The invention will be understood by reference to the annexed drawing, inwhich-- Figure 1 is a plan of the roof of a revolving door with thetrack removed over one of the casing-walls, which is adjusted at theside of the passageway, the other casingwall being shown in its closedor shifted position; Fig. 2 is an elevation of the revolving doorcasingviewed from the direction of the arrow 8 in Fig. l, with the corniceSpecification of Letters Patent.

omitted, and the casing-wall at the right slde moved to its closedposition, and the roof shown in section on line 2-2 in Fig. 2; Fig. 3 isa plan of a revolving door with the roof of the casing removed and theentire casing-walls movable; Fig. 4 is a similar plan with only half ofeach casing-wall movable to close the passageway; Fig. 6 is a sectionnear the edge of the movable wall on line 55 in Fig. 5, the view beingbroken for want of room upon the drawing; Fig. 5 1s a longitudinalsection on line 66 in Fig. 6.

In Figs. 1 and 3, a partition or exterior wall A is shown having apassageway therethrough to which the casing of the revolving door isfitted movably.

In Fig. 3, the casing-walls a, a are of the usual segmental form, thewall-segment a being shown in its normal position at the side of thepassageway, and the entire wallsegment a moved so that its forward edgeextends half way across the entrance to the door; so that when thewall-segment a is similarly moved the entrance to the door would bewholly closed. When the forward edges of the segments are thus arrangedtheir rear edges are adjacent to the partition A and thus prevent accessto the passageway.

The passageway through the wall A in Fig. 3 equals the diameter of thecasing so that it cannot be closed without moving the entire quadrantalsegments a and a; but Fig. 4: shows a wall B with the casing set insidethe same, so that the passageway C may equal one-quarter the periphery fthe casing, and be readily closed by partial segments of the side-walls.

The casing-walls, which are usually quadrantal, may therefore be dividedeach into two equal segments, the rear segments a being fixedstationary, and thus aiding to support the roof of the casing; while thefront segments a are adapted to slide forwardly into contact with onenether, as shown in Fig. 4, and close the passageway C.

A box 6, containing a yielding packing 7) is shown upon thepartition-wall B at the edges of the passageway C, to engage the forwardedge of each segment a when in its normal position, and their rear edgeswhen in their closed position, to exclude air when the doorway isclosed.

With both the constructions shown in Figs. 3 and 4, the door-wings 0which are carried by a central post (Z, revolve with their edges not farfrom the edges of the opening in the exterior wall, and thecasing-segments are movable between the edges of the doorwings and theedges of the said opening, so that they may be slid across the openingwhen required.

Means are provided upon the roof of the casing to guide thewall-segments when moved, the roof D being formed with a segmental slotf through which hangers e are extended from the tops of thewall-segments and thus guide the upper ends of the segments. A curvedbar g is shown attached to the floor and fitted to a groove in thebottom of each of the wall-segments to guide their lower ends. A track fis provided upon the roof above the slot f, to which track-wheels on thehangers are fitted, and the wall-segments are thus hung and sustainedmovably upon the roof.

Where the entire wall-segments are movable, the roof is necessarilysupported and braced by suitable means which are not shown herein, asthey vary with each installment. The walls are also held fromdisplacement in either position by lockingbolts 71- and 72, projectedfrom the upper and lower ends of the movable segment into the roof andfloor respectively.

Holes 6 are shown in the floor in Figs. 3 and 4, and holes j in theroof; and Figs. 3 and 4 show the bolts h in the upper ends of the wings,which are adapted to fit the holes j in the roof to secure the movablesegments in either position.

Figs. 5 and 6 show the bolts fitted within the body of the segment and acrank-plate 7a sunk in the segment flush with its surface and connectedwith the bolts h and h by pin and eye-connections Z and Z. A pinion,engaging racks upon the bolts, or any other rotary bolt-mover, may beused instead of the crank-plate k. The crank-plate 7a is journaled in ametallic housing m and has a square or polygonal socket 771/ upon itsinner side only, into which a wrench of suitable form can be fitted toturn the crank-plate and throw the bolts into their respective holes.With this construction, the locks upon the two segments are inaccessiblefrom the outer side when the doorway is closed, and the fixtures areflush upon the inner sides of the segments so as not to interfere withthe rotating wings. The mere shifting of the bolts permits the segmentalwalls to be moved into either required position, and locked securelytherein.

Where the side-walls of the casing are movable across the passageway asshown herein, they cannot be held so rigidly as if permanently fixed atthe sides of the doorwings, and are thus liable to be a little out ofplumb or concentricity with the spindle of the wings, for which reasonit is desirable to furnish a packing for the edges of the door-wingswhich will compensate for any inequalities in the surface of thecasingwalls, and this is provided by the sectional packing shown herein.

It is obvious that where access from the exterior of the building isdesired through the revolving door after the segments are locked acrossthe passageway, a lock must be used as upon ordinary doors, havingakeyhole upon the outer side by which the bolts upon one or both of thesegments may be moved to permit the opening of the same.

It is obviously immaterial what form of lock be employed to secure thesegments in their opened or closed position, and a mere hook and eye toengage the two segments with one another would sufiice if a stop wereprovided upon the roof of the casing, as shown at w in Fig. 2, adaptedto arrest both the segments when moved to their closed position.

Having thus set forth the nature of the invention what is claimed hereinis:

1. The combination, with a wall having a passageway therethrough, of arevolving door having radial rotatable wings to exclude dust and wind, acasing having wallsegments operating in a fixed position at oppositesides of the passageway in cooperation with the rotatable wings whenpassengers are moving through the same, and movable into a fixedposition across the passageway when required to close the same.

2. The combination, with a wall having a passageway therethrough, of arevolving door having radial rotatable wings to eX- clude dust and wind,a casing having wallsegments operating in a fixed position at oppositesides of the passageway in cooperation with the rotatable wings, andmovable across the passageway to close the same, and means for securingsuch segments across the passageway to bar passage therethrough.

3. The combination, with a wall having apassageway therethrough, of arevolving door having radial rotatable wings to exclude dust and wind,casing-walls formed each in two segments arranged in a fixed position atopposite sides of the passageway when the door is in use, and detachableseg ments of such walls movable across the passageway to close the same,and provided with means for securing them in such closed position to barthe passage through the passageway.

4. The combination, with a wall having a passageway therethrough, of arevolving door having radial rotatable wings to exclude dust and wind, astationary roof supported above the wings to sustain a bearing therefor,wall-segments operating in a fixed position between the floor and saidroof at In testimony whereof I have hereunto set opposite sides of thepassageway in cooperamy hand in the presence of two subscribing tionwith the rotatable wings when passengers are moving through the door,and witnesses.
